FAQ

What is the lug width of the Omega De Ville Sedna Gold 434.58.34.20.55.001?

The lug width of reference 434.58.34.20.55.001 is 16mm. This width, measured between the two lateral lugs of the case, is a constant of this model and determines which straps are compatible. 18mm or 20mm straps will not fit correctly on this case.

Which strap do you recommend for the De Ville 34mm Sedna Gold?

For the Sedna Gold 34mm we primarily recommend alligator with vegetable tanning, which complements the chiseled dial discreetly without competing with the case. Alternatively, French calf with vegetable tanning for a soft hand feel and natural patina over time, or shell cordovan for those who desire a robust strap that ages with character.

How do you change the strap on an Omega De Ville?

The strap is changed via the two lateral spring bars that run through the case lugs. Using a spring bar tool, you compress the elastic pins, remove the old strap, and insert the new one, ensuring the pins are aligned symmetrically. We recommend performing this operation on a soft surface to avoid scratches on the Sedna Gold case.

Can I use an aftermarket strap on this Omega?

Yes, provided it has the compatible 16mm lug width. Milano Straps offers a complete collection of aftermarket straps in various materials and colors, all designed to fit perfectly the 16mm lugs of your De Ville 434.58.34.20.55.001, without any modifications to the case.

How long does a leather strap last on a watch worn daily?

A high-quality leather strap with vegetable tanning and artisanal construction typically lasts 3-5 years of daily use, depending on exposure to water, humidity, and mechanical stress. Shell cordovan tends to last longer thanks to its natural hardness. Patina is a natural aesthetic process that increases the character of the strap over time.
